Our invention relates to hose nozzle constructions.

The object of our invention is to provide a construction suitable foruse in extinguishing fire in buildings or marine vessels, or brush andforest fires, and which may also be used for spraying lawns and foliage,etc.

The principal object of our invention is to provide a constructioncomprising a body portion and a sleeve movable thereon adapted tocontrol a narrow slot or slots formed in the body portion thru whichliquid is forced in the form of a thin sheet or sheets which serve as ashield for the user and serve to assist in extinguishing a fire whendirected thereon.

A further object is to provide a construction whereby the liquid forcedthru the slot or slots may be directed at an angle to the normaldirection of flow therethru and caused to be directed in an outwardlyextending inverted coni- I cal form, the volume of which is controlledmanually by operation of the sleeve which also serves as a valve bymeans of which the slots may be entirely closed.

A further object is to provide a body portion 2 having slots extendingfrom the bore of the body portion in a lateral direction and arranged inconcentric rows spaced a short distance apart longitudinally, the slotsarranged in one concentric row extending beyond the ends of the slots inthe adjacent rows and thus serving to form a complete circular shield ofwater when in operation, said sheet being thin enough for objects to beeasily seen therethru.

A further object is to provide a construction in which interchangeabledischarge snouts may be used for the purpose of reducing the volume ofwater discharged from the main bore, and also to change the form of thestream as it issues from the bore, as would be the case when the shoutillustrated in Fig. 4 is used in fighting brush fires.

It will be understood that made in various sizes for use for stand-pipeservice.

Referring to the drawing forming a part of the specification:

Fig. 1 is an illustrative view of the appearance of the device.

Fig. 2 is a longitudinal sectional view of the device in which thesleeve is shown as designed to serve as a valve to close the slots inthe body portion.

the device may be with garden hose, or

Fig. 3 is a sectional view of a nozzle snout formed with a smallerdiameter of outlet than that shown in Fig. 2.

Fig. 4 is a sectional view of a snout designed for use in extinguishingbrush fires, and for use in small rooms of buildings or marine vessels.

I0 indicates'the shank portion of the device, H the body portion, l2 thesleeve, and I3 the snout shown carried by the body portion.

It will be obvious that the snout and body portion illustrated in Fig. 2may be made integral if desired, but when so made the snouts would notbe interchangeable for use with the body.

The butt end of the shank (not shown) may be formed as a coupling orother desired means for securing it to a hose in the usual manner. Thepassage or bore M of the shank I 0 is usually formed with converginginner walls, and said shank is coupled with the near end of the bodyportion at M by a threaded engagement as shown, but it may be coupled inany other practical manner designed to hold the parts together inseparable relation.

As illustrated in the present case, the body portion is provided with athread formed in its outer cylindrical surface, indicated by Hi, whichserves to unite the shank and body portion, and also serves to guide thesleeve which engages therewith and is rotated thereon in the act ofopening the slots [6 formed in the body portion.

In the drawing the slots are shown as formed in three concentric rowsspaced a predetermined distance longitudinally from each other, each rowhaving a plurality of narrow slots, the ends of which are spaced fromeach other -a predetermined distance.

The adjacent row of slots are so arranged that the slots extendcircumferentially beyond the ends of the first row, the respective rowsbeing indicated by ll, l8 and I9.

The outer surface of the body portion H is shown as formed with aconical end portion 20 in which the slots are located, and the sleeve I2is formed to fit closely over said surface and close the slots when inone position as shown, and to open them when the sleeve is retracted,the degree of opening depending on the position of the sleeve.

When the sleeve is partly retracted, the liquid under pressure will flowthru the slots and combine in an annular space formed, and a sheet ofliquid will be directed outwardly therefrom in a conical formation, thevolume of liquid depending on the degree of opening.

When the sleeve is entirely retracted, the

liquid will flow laterally from each slot, the combined sheets forming acircular shield.

The bore thru the body portion may be tapered as illustrated, or may bea straight cylindrical form, but in either case the snout is made with abore of smaller diameter so that a back pressure is created at the areain which the slots are formed to insure a proper discharge of liquidthru the slots Without materially reducing the liquid discharge from thesnout.

The degree of taper of the conical end portion may be reduced orincreased to any desired degree in making the device, or may bedispensed with in case where only the direct laterally flowing sheets ofliquid are to be discharged, it being understood that the sleeve is alsochanged to closely cover the slot or slots to close the same.

The forward end of the body portion is provided with a thread at 2| toengage a similar thread 22 formed on the snouts.

The sleeve is formed to provide a cover portion I2 which serves to coverthe threaded portion of the body at H when the sleeve is in the positionshown in the drawing.

Referring now to Fig. 4 in which is illustrated a snout portionconstructed to form streams of water suitable for use in extinguishingbrush fires.

It is made by first casting in a mold to the outward and inner formsubstantially as illustrated, with a semicircular rib 23, after whichthe outer surface is turned smooth, and then a number of circular slotsare formed which extend entirely around and thru the wall of the castingand are formed to discharge a liquid at relatively different angles, aswill be readily understood by those skilled in the art of making hosenozzles.

The rib 23 serves to hold the circular rings 24 in their relativeposition after the slots are made in the casting.

The slots may all be of the same width or may Vary relative to eachother within a limited degree but their combined outlet area should beless than the area of the bore in the body portion, and this holds truewith respect to the slots formed in the body portion also.

It will be noted that a plug may be attached to the body portion inplace of a snout when the device is made for the purpose of a lawnsprinkler and mounted on a stand which supports it in a verticalposition in the usual manner of supporting such sprinkling devices.

It will also be understood that the body portion with the sleeve andsnouts, may be made as independent articles of manufacture, and sold foruse with a shank such as illustrated in the drawing; also that in smallsize nozzles the thread formed on the body portion and sleeve may bedispensed with if desired and the sleeve fitted to slide in closecontact over the body portion to open or close the slots, as will bereadily understood.

It will also be noted that the tapered main bore is smooth andunobstructed, thus insuring a free delivery and long throw of water fromthe snout when operated under high pressure.

Having thus described our invention we claim as new:

1. A hose nozzle construction comprising a body portion having anunobstructed passage therethru and having a plurality of series ofnarrow slits located between the inlet and outlet of said passage, saidslits extending at substantially right angles to the median line of saidpassage and being arranged in circular lines circumferentially of saidbody portion, the ends of each slit of one row extending in front of theends of slits of the adjacent row, to cause liquid forced thru saidslits to form a complete circular protecting shield of very thin flattransparent sheets of liquid surrounding said nozzle at substantiallyright angles thereto and through which objects may be discerned, and asleeve movable on said body portion to open and close said slits.

2. The construction defined in claim 1, together with the outer surfaceof said body portion flaring toward its forward end and said sleevebeing shaped to conform thereto and being movable rearwardly to opensaid slits and forwardly to close the same.

3. A hose nozzle construction comprising a portion portion having anunobstructed passage therethru and having a series of narrow slitslocated between the inlet and outlet of said passage, said slitsextending at substantially right angles to the median line of saidpassage and being arranged in circular lines circumferentially of saidbody portion, the end of a slit in one circular line extending in frontof the end of a slit in an adjacent line, to cause liquid forced thrusaid slits to form a complete circular protecting shield of very thinfiat transparent sheets of liquid surrounding said nozzle atsubstantially right angles thereto and thru which objects may bediscerned, and a sleeve movable on said body portion to open and closesaid slits.

4. The construction defined in claim 1, together with the outer surfaceof said body portion flaring toward its forward end and said sleevebeing shaped to conform thereto, said sleeve being in threadedengagement with said body portion and being movable rearwardly to opensaid slots and forwardly to close the same and into an intermediateposition to transform said shield into a conical form by passing betweensaid flaring body and sleeve portions.
